Officials found Benjamin Authier dead Wednesday in the water at Hippie Hole. The Rapid City Journal reports that Authier was a chemical engineering major at the South Dakota School of Mines and Technology.

Authier was reported missing Tuesday evening, and his car was found at a parking spot used by visitors of the swimming spot. Authorities searched until it was too dark, and officials found Authier after resuming Wednesday morning.

Tony Harrison is patrol division captain for the Pennington County Sheriff's Office. He tells the newspaper that it appears Authier was alone and came to the area to snorkel or swim.

Harrison says there weren't signs of foul play, but authorities are investigating.
